The Active Directory Connector (ADC) that comes with Microsoft Windows 2000 replicates only the site naming context information whereas the ADC that comes with Exchange 2000 replicates the site naming context and the configuration naming context information.
If you are planning to have a mixed site with Microsoft Exchange Server 5.5 and Exchange 2000 server, use the ADC that comes with Exchange 2000. The ADC that comes with Windows 2000 cannot replicate the configuration naming context and therefore, cannot be used.
If you want to synchronize the mailbox objects between Exchange Server 5.5 and Active Directory, you can install the Windows 2000 ADC and create a Connection Agreement. You can choose to use the Exchange 2000 ADC in this case because it also replicates the site naming context.
